HP Storage Essentials NAS Manager Software - Manual (Page 618)

Finding an Element’s Storage Capacity 586
Keep in mind the following:
• Verify the performance collector for the element is enabled (Optimize > Storage Essentials >
Performance Data Collection
). See ” Managing Performance Collection ” on page 227 for
more information about enabling performance collectors.
• Switches and storage systems display data from the last time Discovery Data Collection/Get
Details was performed. See ” Step 1 - Discover Switches ” on page 34 for more information.
• If you see “There is not enough data to produce a chart [chart_title] at this time.” message,
lessen the frequency option, so that the amount of time listed in the Frequency drop-down menu
has passed before you view the chart again. For example, if the Frequency menu displays
hourly, you need to wait an hour for data to appear in the chart.
